目标C中的AES加密技术

Question

我正在做一个项目，我必须与.net团队协调。我需要目标 -C 中下面提到的 AES 加密算法（用 C# 编写）的等效代码。我试过使用AESCrypt和CommonCrypt，但它并没有很好地醒来。在两种语言中获取不同的加密值。

private string Encrypt(string clearText)
{
    string EncryptionKey = "MAKV2SPBNI99212";
    byte[] clearBytes = Encoding.Unicode.GetBytes(clearText);
    using (Aes encryptor = Aes.Create())
    {
        Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(EncryptionKey, new byte[] { 0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76 });
        encryptor.Key = pdb.GetBytes(32);
        encryptor.IV = pdb.GetBytes(16);
        using (MemoryStream ms = new MemoryStream())
        {
            using (CryptoStream cs = new CryptoStream(ms, encryptor.CreateEncryptor(), CryptoStreamMode.Write))
            {
                cs.Write(clearBytes, 0, clearBytes.Length);
                cs.Close();
            }
            clearText = Convert.ToBase64String(ms.ToArray());
        }
    }
    return clearText;
}

请帮忙..感谢在爱德瓦斯

在回答使用 CCKeyDerivationPBKDF 代替 Rfc2898DeriveBytes 时：

使用Common Crypto的PBKDF2的简单C示例。
将C++字符串转换为字节数组时应小心，通常在转换中使用 UTF-8。

const char  passwordData[] = "password";
size_t      passwordLength = strlen(passwordData);
uint8_t     salt[]         = {0x01, 0x02, 0x03, 0x04};
size_t      saltLength     = sizeof(salt);
uint        rounds         = 1000;
const int   derivedKeySize = 16;
uint8_t     derivedKey[derivedKeySize];
CCKeyDerivationPBKDF(kCCPBKDF2,
                     passwordData, passwordLength,
                     salt, saltLength,
                     kCCPRFHmacAlgSHA1,
                     rounds,
                     derivedKey, derivedKeySize);
for (int i=0; i<derivedKeySize; i++) {
    printf("%2x ", derivedKey[i]);
}
printf("%s", "n");

输出

31 96 42 56 3F 7F B3 91 3E 85 FA 43 39 5E 69 93
